Let . Then which of the following is true?
principle of mathematical induction can be used to prove the formula
As we learnt in
Steps of Mathematical Induction (Verification step) -
Step 1: Verification step
Actual verification of the proposition of the starting value
is divisible by 7
Put n=1, It Satisfies.
Steps of Mathematical Induction (Induction Step) -
Step 2: Induction Step
Assuming the proposition to be true for n=k, and proving it is true for value
Steps of Mathematical Induction (Generalization Step) -
Combine Verification step and Induction step
is true and is true for assuming it is true for
Which is not true
is not true
S (k) is true
